Answer:
AAAB.
Step-by-step explanation:
A rhyme scheme can be defined as the pattern of the rhyme used by the poet in a poem. This pattern can be seen at the end of a line or a verse. In simple terms, a rhyme scheme is a pattern of the words at the end of each line or verse in a poetry.
"Birmingham Sunday" is a poem written by Richard Farina. The poem speaks about the bombings in Birmingham occurred on 15th September 1963.
The rhyming scheme that Richard Farina has used in the poem is AAAB. It is because the last words of each line ends with the words 'blew', 'two', and 'knew.' These words rhyme with each other and the last word of the line four 'freedom' does not rhyme with any word. Thus the rhyme scheme is AAAB.
So, the correct answer is AAAB.
